Orbit 4SB-MKO-WB 4" Square Welded Box with MKO & WB Bracket, Pack of 100

Orbit 4SB-MKO-WB 4" Square Welded Box with MKO & WB Bracket

The Orbit 4SB-MKO-WB is a 4" square (4S) welded outlet box built to a 1-1/2" depth and factory-equipped with an MKO mounting knockout configuration and a WB bracket for fast, secure rough-in installation. This welded 4-square box is a staple for electricians who need a rugged, code-familiar enclosure for switch, receptacle, and junction applications in new construction and remodel work. The integrated WB bracket allows the box to be positioned and fastened to framing members quickly, reducing installation time on the jobsite while keeping the box square and properly set for device or cover plate installation. As a welded (rather than stamped/one-piece) 4S box, it offers the solid, rigid construction electricians expect from a general-purpose square box used throughout residential, commercial, and light industrial wiring.
